Application:By using the products widely in insulating layers of various
thermal equipments, for example, blast furnace, hot blast furnace,
coke oven and linings, no high temperatures melt corrosion occurs.Features:It is characterized by low bulk density, maximum service
temperature of 1350C., high cold crushing strength, size precision
and the most stable and lowest thermal conductivity of all
insulating refractory bricks at present.The total weight of the furnace body and the thickness of the walls
can be reduced effectively, thermal efficiency and working
condition can be improved, energy consumption can be lowered, and
productivity and significant economic results can be achieved.High alumina lightweight insulating refractory brick is a kind of
insulation material adopting organic matter as ignition loss
substance in order to increase the porosity of refractory. It has
such advantages of high porosity, small volume density, good
insulation effect, high mechanical intensity, small thermal
conductivity and long service life. For various industrial kilns
& furnaces, it is a kind of essential refractory for energy
saving and temperature preservation.Composition:This series of High Alumina Insulating Refractory Brick are made of
selected high alumina bauxite, kaolin clay and hollow microsphere
by shaping at high pressure and sintering at high temperature.
